How can PHP interact with user input from HTML forms to pass as parameters to functions?

To interact with user input from HTML forms in PHP, you can use the $_POST or $_GET superglobals to retrieve the form data. You can then pass this user input as parameters to functions in your PHP code to process the data accordingly. 

<?php
// Retrieve user input from HTML form
$userInput = $_POST['input_name'];

// Define a function that takes user input as a parameter
function processInput($input) {
    // Process the user input here
    echo "User input: " . $input;
}

// Call the function with user input as a parameter
processInput($userInput);
?>
